Passive 6850

Is this recommended for a silent build?

Or will it create too much heat?

Using one right now. Only gets up to a little over 80c when playing Crysis: Warhead.

(Case: Antec P182, System Fans: 3x Scythe Slipstreams @ 400RPM, 1x intake, 1x CPU heatsink, 1x exhaust, nothing on the GPU heatsink)

Probably unwise to use it in a fully passive build, but as long as you've got a little airflow going through the case, it'll work well. :)

If you have not much case airflow, you might want to zip-tie a pair of very slow 12 cm fans to make it happier: the extra noise will be unnoticeable.

I've got one also. Zipped a low-speed, inaudible Noctua to it. Temp never exceeds 60C, even when playing Crysis, incredible. I'm very happy with it.

Got a zip-tied Slipstream 1200 rpm at <5 V (read: inaudible) on my Radeon 5750. Can only recommend it! Temperature only went as low as 56 C during Furmark, and my case has next to no airflow. Without the fan it reached 95 C and continued to rise if I didn't shut down Furmark. I can really recommend zip-tying a fan, especially on the 6850 which is undoubtedly hotter than my 5750.

I think a Slipstream Slim version fould fit perfectly because of its thinness. But not that necessary if you don't use other expansion slots.

That one is very quiet once you manually set the fan speed to 30~35%. Mine was about as smooth and quiet as the 400RPM Scythe Slipstreams I had in the rig at the same time, quite impressive. :)
